My Chevy truck is stuck in 4-wheel low. It has knob controls. I tried unhooking the battery overnight to see if that would reset it, but it's still stuck.
I had that happen to my 20001 GMC Sierra truck, basically the same as a Chevy. Mine has push button 4 wheel drive and in my case the push buttons had to be replaced. I don't know how that translates to knob controls.
You have to get inside of it all and see where it's stuck. Only then will you know if it's fixable. Clean everything first though. It might be as simple as that.
